Backlight assembly and liquid crystal display device having the same

Abstract

A connection of electrode lines of lamps for supplying a light source for a backlight assembly of a liquid crystal display (LCD) device is improved to minimize the size of the LCD device while reducing the manufacturing cost. The LCD device includes the backlight assembly having a light emitting unit formed by plural lamps for generating light and a light controlling unit for guiding the light from the light emitting unit, and a display unit placed to the upper plane of the light controlling unit for receiving the light from the light emitting unit via the light controlling unit to display an image. A driving unit is further provided for converting an external power source of a DC component into an AC component to supply first and second driving signals having phases respectively different from each other to the light emitting unit. Plural lamps respectively have two electrodes which include a first electrode directly connected to the electrode of at least one adjacent lamp and selectively have a second electrode supplied with the externally-provided driving signals. Thus, the wiring of the electrode lines of the plural lamps is simplified to decrease the size of the backlight assembly and LCD device while reducing the manufacturing cost.
